The Emerald Estates trails network is often referred to as the No Flow Zone. It is a large area consisting of a variety of technically challenging trails. Most of these were built by local builder Dan Swanstrom, who seems to have an eye for coming up with some very technically challenging trails. I’ve been told that he is also the man behind trails such as River Runs Through It and Danimal; some of my personal favourites. The trails in the No Flow Zone are accessed from Emerald or via Alpine Meadows using the Delineator connector. The area will not appeal to all riders, yet those who love the old school style of riding, super technical singletrack, will enjoy the trails located here. The trails are all connected and accessed via Shit Happens, the main artery which encircles the area, and most were built to be ridden in both directions. The riding here is raw, rough and challenging, as many of the routes are rated advanced to expert. The singletrack is made up of rock, roots, boulders and more rock. In fact there is a substantial amount of rock found on almost all the trails, making this area a real challenge to ride without coming off your bike. Big rocks, jagged rocks, tire piercing rocks and some amazing steep rock slabs are the flavour here. Personally I really enjoy riding this area and love the challenge of trying to clean many of the routes. Once you’ve ridden here a few times, you will actually start to find your flow and will grow to appreciate how much your riding has improved. Not to mention that the area doesn’t see too much traffic, making the riding here a great way to connect with nature.

The access to this area is via Emerald Drive when pedaling from Emerald Estates or by using the Delineator connector if coming from Alpine Meadows. As mentioned, the main artery in this network is Shit Happens. Ride Shit Happens on its own or in combination with several other trails; including Big Kahuna and Anal Intruder. Bring your “A Game” and at least one spare tube, to ride this area. And don’t forget to scroll below the photos for links to individual trail descriptions that make up the No Flow Zone, along with suggested loops.

Option 2: This advanced point-to-point ride finishes at Sixteen Mile Creek FSR (Cougar Mtn Road) from where you can connect with Kill Me Thrill Me and continue to ride north if you’re looking to extend your ride.
